Application filed June 8,

"certain new and useful Improvements in Mop Pails and Wringers; and I dohereby `declare the following to be a full, clear, and

exact description of the invention, such. as will ena-ble others skilledin the art to which Iit appertains to make and use the same.

This invention relates toa mop pail and wringer device therefor. Suchdevices are now extensively used and usually comprise a` liquid-holdingpail or receptacle and a wringer device at the top thereof comprisingrelatively movable rollers between which the mop is squeezed after beingrinsed or "dipped in the pail.

It is an object of this invention to provide such a device having afixed or local roller ,and a `movable roller movable toward the fixedroller in a downwardlyV inclined direction to more efficientlysqueezethe mop.

It is afurther object of the invention to provide a track or cam meansfor guiding the movable roller toward and from the `fixed roller, whichmeans comprises'adown- `wardly extending portion adjacent the fixedroller.` It` is still another object of the invention to provide mopguiding means or guards which are shaped to conform to the contour ofsaid track or cam means.

`These Aand other objects and advantages "of the invention will be fullyset forth in the `following description made in connection with theaccompanying drawings iii whichlike reference characters refer to thesame parts throughout the Vdifferent views, and inwhich,

Fig. l is a View inside elevation of the device; i i p i `F ig. 2 is atop plan view thereof;

Fig. 3 is a vertical section taken on the line 3--3 of Fig. l, and shownon an enlarged1 scale; and j Fig. i is an end view of one of the rollerspartlyin section also shown on an enlarged Y scale.

l Referring to," the drawings, the j device comprises a pail or liquidholding receptacle l, W'hile this pail may be of any desired l shape`the same is illustrated as being substantially rectangular or square incross section `and is provided at its top edge with a rolled; wirecontaining bead. This pail has .1922. `serial iro. 566,688. i

a bail 2 secured to and extending along the sides thereof at the bottom,said bail having a forwardly projecting portion 3 adapted to contactwith the Hoor or supporting surface for .the pail. The bail 2 isprovided with an outwardly bent portion substantially centrally of the-sides ofthe pail l which is spaced slightly from the pail, whichportion is adapted to hold foot plates 4 having U-sliaped side portionsadapted to hook over the side of the bail and be disposed between thesaine of the pail.

Straps 5 are provided at the tops of the sides of the pail and aresecured at one end to plates 6 disposed at the outside of and secured tothe pail sides, which plates have horizontal portions extending over thesides to which the straps 5 are attached. These straps are formed withloops or eyes at their forward ends forming the bearings for the endjournals of the fixed or local rolleiI 7.. The straps 5 extend in ahori-l and the sides' of Azontal rearwardly direction a short distancefrom the roller 7 andtheii extend upwardly `in a rearwardly inclineddirection and are curved to again extend `downwardly to the rear .of thepail and which are secured to the inside thereof. A movable roller 8 hasprojecting end journalsextending across the top of the straps 5 andsmall U-'shape-l clips 9 extend under thegstraps having ears projectingupwardly at the sides thereof .apertured to receive the journals of theroller 8. Journals are thus held substantially in contact with thestraps 5`which `form tracks therefor. Rigid arms l0 extend across theends of the journals of the roller 8 and have their upper ends curved toextend over thetraclrs 5 and clips 9, said ends extending` downwardlyand "being 'apertured to receive the journals of the roller 8 adjacentthe ends of said roller. The Y arms 10 extend along the outside of thepail and are pivoted at their other ends to the outside of the treadlebail 11 which embraces the sides of the pail and extends forwardlythereof where it is provided with a tieadle plate 12. The pail has angleplates 13 secured thereto at the rear corners thereof adjacent its topand said plates are provided adjacent their lower ends with pressed-outconical portions 14 adapted to receive the heads of pivot bolts 16 onwhich the ends of the bail ll are pivoted and on which they are held bysuitable nuts lil applied to said bolts. Coil'ed springs 17 are securedto the plates 13 adjacent the tops thereof and attached at. their' othervends to' the treadle bail 11 adjacent its pivotal points.

A pair of mop guiding members or `gaiards 18 are provided and secured tothe inner sides of the pail at the rear and top thereof and are extendedforwardly to the front side of the 'pail to wliich'their inturnod endsare bolted. These gua-rds are shaped to conform to the contourofthe'tracks 5, being spaced ysomewhat below the same. The pail 1 isprovided with attaching ears at itssides to which is pivo'ted handlecarrying bail 19.

The rollers 7 and 8 are preferably'fornied of pressed'sheetinetaltubing, as shown in Fig. 1, the ends of Vwhich arevcrimped andclamped'to the disks 2O carrying the'project'ing journals Q1.

1n operation, the springs 17 holdi the bail 11 normally elevated, asshownin Fig. 1, and the arms 10 will then be inclined'ifearwardly and'the roller 8 held in position adjacent the rear ofthe pail 'or atltheside thereof opposite tlieroller 7. lfVhen it is desired to squeeze themop, the same will be inserted in the top ofthe pailI between the.members 1 8. The foot will then be placed upon' the plate 12`andltreadle bail 11 depressed 'to V',sr-.bstantially the position shown inVdotted linesA in Fig, 1. 1f desired, -the other foot can be vplaced'upon one of the foot plates VLfwhe'n the bail is so pressed. Then thebail 11 is pressed downwardlythe arms 10 cause the vroller 8 to movetoward the roller Y and to'follow the lcontour vof'l the tracks 5. Therolleris thus firstI` elevated and is then moved' downwardly as itapproaches the fixed'roller 7 so that a downward squeezing pressure is'exerted on the mop. r1`his downward 'squeezing pressure acts veryefliciently to squeezethe water and dirt fromvthe mop, and produces a"wedging action of the rollers. r1`he movable roller is not only moveddownwardly but is cam'ined forwardly by tracks 5, thus giving a veryeffective action. y lllhe arms 10 being connected near thefront Vof bail11,y a great leverage is obtained, giving a heavy pressure on therollers. When the pressure on the treadle bail 11 is released the partsresume their normal position shown in full lines in Fig. 1. rllheprojecting bail 2 acts to stabilize the pail and prevent overturning ofthe saine by pressure applied to the bail 11.

From theabove description it is seen that applicant has provided asimple and 'inexpensive mop pail and wringer and 'one which acts veryefficiently to'squeeze the mop. The

parts of the devicelare all easily'niade from standard material whichcan be easily obtained.

1t will, of course, be understood that various changes may be made inthe form, details and arrangement vof the parts without departing fromthe scope of my invention, which, generally stated, consists in thematter shown and described and set forth in the appended claims.
